SLUECING DEVICE.

Application led July 12,

To all tf1/tom it may concern:

Be it known that l, Bonner d. lilo-Geni.- LAND, a citizen oi the UnitedStates, and resident of llniiurst., Long island, in the ity of Queens,city and State oi New Yorlr, have invented certain new and usimprovements in Sluicing llevices, of which the tollowing is aspecification. f

rlhis invention relates to a sluicing du vice for filter presses and hasfor its primary object to provide a simple and effective vinsane forremoving the coagulurn or calrc formation which collects upon the iltercloths of filter presses such for instance as are used in theproce/estoie reiining sugar.

fis is well known in the art, in the refineinent of sugar, the collectedinaterial adhering to the exterior surface oi the lilterV cloth isremoved hy ineens of wash water discharged from a A extending' into thefili; 2r casing This pipe is longitudinally niovahlo and is likewiseoscillated in order that the discharged water will strike the iltercloth over its entire area. t

lt is the primary object and purpose of present improvement to provide adevice of this nature wherein means is employed lor automaticallyreversing the reciprocation of the wash water pipe at the end or itsstroke in each direction so as to ohviate the necessity oi employing anattendant to manually operate the water pipe.

W ith the alcove and other objects in viewa the invention consists inthe improved automatic sluicing device and in the form, proportion andrelativel arrangement of its several parts to loe hereinafter'rnoreiully described, illustrated in the accompanying drawings andsubsequently incorporated in the suhjoined-clairns.

ln the drawings wherein l have disclosed one simple and practicalembodiment of the invention and wherein similar reference charactersdesignate corresponding parts throughout the several views:

Figure 1 is a side elevation partly in section showing a preferred'torni oit the invention;

l*1 igure 2 is a section taken on the line 22 of Figure 1, and

-Figure 3 is a fragmentary elevation showing the manner of reversing theratchet engaging pawl.

Referring in detail to the drawings, 5 des- 1921. Serial No. 4347177.

ignates the longitudinally reciprocating and oscillating wash water pipewhich extends into the il''er press, a portion of which is indicated at6. The pipe 5 is connected to a fixed pipe section 7 through 'theinediuin of a sleeve 8 which is provided with suitable packing toprevent the escape of the water, while permitting of the relativemovement oit the pipe 5. y

Upon the pipe 5 an eirteriorly threaded sleeve 9 is securely iixed byone or more set screws 10. A nut 11 has threaded engagement upon thesleeve 91, said nut being integrally connected at one oi" its ends hymeans of the radial arms 12 to a wheel 13 the outer peripheral face ofwhich is provided witli a continuous annular groove le. Upon theopposite end of the nut 11 an annular flange 15 vis iornied and to t eend tace ci said nut a colla-r1.6 is rigidly fixed and has a flange 1'?spaced fronithe flange 15. The space between these flanges receives aring or annulus 18 which is coni nected by a plurality of bolts 19 to alined part ol the iilter press. The ring 18 thus holds the nut 11against a longitudinal moveinent with relation to the sleeve 9 whileperinittin@ ci.3 its rotation upon said sleeve.

To the arms l2 of the wheel 13.3 ratchet wheel 20 is securely bolted orotherwise rigidly Vfixed, The teeth 21 ot this wheel are of less widththan the width oi the wheel and terminate in spaced relation to itsopposite side edges.` Y

Upon the pipe 5 an arin 22 is securely .tlxed by means oit the clamp 23or equivalentdevice and in one end of this arin the pin 24 is mounted. Apawl 25 is loosely engaged upon the end ci the pin 24' and to each sideof said pawl and at opposite sides of the axis of the pin 24: a pair ofspaced lugs 26 are fixed. W ith the respective pairs ci. lugs, radiallyprojecting tinge-rs 27 secured upon the peripheral face of the wheel 20at relatively opposite sides of the teeth 21 are adapted to coact in amanner to loe later explained.

The clamp' 23 for the crank arm 22 is provided with a radially extendinglever 28 upon which the collar 29 is fixed. A `connecting rod 30operated by a power driven crank (not shown) is ilexibly connected tothe collar 29 by means of a link` 3l, a, sinn ilar linlr connecting theother end or' said rod to the oWer crank. These links transmit anoscillating movement to the water pipe 5 in the reciproeation of the rod30 and also permit of the longitudinal movement of said pipe.V 'Thecollar 29 may be readily adjusted on the lever 28 so as to regulate theoscillation of the pipe.

lt Will be noted that the paivl 25 is provided at its free end and atthe opposite side edges thereof with lugs 32. @ne of these lugs isadapted to coact .vith the ratchet teeth 2l when the paivl is disposedat one side of the crank arm as shown in full lines in Figure 2, Whilethe other of said lugs coacts with the ratchet teeth When the paivl isreversed and disposed on the opposite side of the crank arm asillustrated in dotted lines.

A friction brake band 33 is engaged upon the base Wall of the groove inthe .vheel lf3, the ends of said band being connected in spaced relationtoV each other to a grooved YWheel 34 mounted to rotate in thesupporting standard 35.' A horizontally entend e' lever 36 is fined atone of its ends to the axis of said Wheel and upon the other end orVsaid lever the Weight 37 .is pivoted.

In the operation of the device, when the pavvl 25 is in the positionshovvn in full lines in Figure 2, upon the doivn stroke of the rod 3Gthe ratchet 2O and consequently, the nut l1 and the `tvheel 13 togetherwithV the pipe 5 and the sleeve 9 are given a partial rotation, thefrictional resistance of the brake band 33 being overcome and all ofsaid parts moving as a unit. ln the upstrolre of theV rod 30 therotation of the iipe 5 is reversed and the pawl 25 moves idly over theratchet teeth 2l. ln such reverse movement, the ratchet 20, the nut lland the Wheel 13 are held stationary by the brake band 33. Vrlhe sleeve9 being fixed upon Ythe pipe 5 rotates with said pipe and with respectto the nut ll with which said sleeve has threaded engagement. The pipeand the sleeve are thus caused to move longitudinally in one directionthrough the nut, the extent of such movement depending upon the pitch ofthe threads and the operating stroke of the rod 30.V ln thislongitudinal movement of .the pipe, the crank arm 22 moves therewith andaccordingly, the pavvl 25 is shifted longitudinally lith respect to theratchet. ln the succeeding doWnstrolre of the rod 30, the rotation ofthe pipe 5 is again reversed and all of the parts move as a unit. It isthus seen that longitudinal movement is imparted to the Wash Water pipe.5 only upon the upstrole of the rod 30. After one complete rotation ofthe ratchet 20 has been made, one pair of the lugs 2G at one side of thepaivl 25 are disposed in alignment with the linger 27 at one side of theratchet wheel so that upon the initial movement of the paw] 25 in areverse .direction on the succeeding upstrolre of the rod 30 one of thelugs 25 will engage the finger 27 as seen Figure 3 of the drawings so asto lriclrvor throw the pavvl to the opposite side of the supporting pinas shoivn in dotted lines in Figure 2 whereby the ratchet will bepositively rotated together with the pipe 5 and sleeve 9 in thecontinued upward movement of the rod. rllhe independent os cillation ofthe vater pipe 5 and sleeve 9 Will now taire place upon the down-strokeof the rod 30 so that the longitudinal movement of said pipe will bereversed. After a series of s .cli operations, the longitudinal movementof the pipe 5 is again reversed by the engagement of thev lugs 2G at theopposite side of the paul 25 with the finger 27 located at the other ideof the ratchet 20. ln this manner it Will be seen that a combinedoscillatory and longitudinal move- 1 ment is imparted to the Wash Waterpipe and at the end of the longitudinal movement in each direction,suchmovement of the pipe is automatically reversed. Therefore, in the use ofthe device in connection with filter presses, no attention Whatever uponthe part of the operator is required. Any desired number of oscillationsof the pipe Vmay he obtained in the longitudinal stroke of the pipe ineach direction by simply varying the spacing of the teeth on the ratchetivheel 2O and the extent of movement of the pavvl 25 in each stroke ofthe connecting rod 30.

l have shown the extreme positions of this paivl when activelyV engagedwith the ratchet teeth in dotted lines in Figure 2, and three suchmovements of the paivl are equivalent to one complete rotation of theratchet. is not of essential importance and the extent of each of theoscillatory movements might be decreased or increased with acorresponding variation Vin theV length of the intermittent longitudinalmovements of the Wash water pipe, Without aecting the principle ofoperation.v By reason ofthe combined oscillatory and longitudinalmovement of the Wash Water pipe, the cake formationvon the surface ofthe filter cloth Will be loosened over the entire area of the filtersurface and dislodged therefrom.

ln the foregoing description and the accompanying drawings, l haveillustrated one embodiment of Vthe device which l have found to be verysatisfactory in practical operation, but it will be understood that theinvention might also be produced inve-.rione otherV alternative 'formsand numerous mechanical changes made in the form, proportion andarrangement of its several parts within the spirit and scope of theinvention as claimed. f
